I am using Metaframe Presentation Server 4.0 and ICA Client 9.0. I have put a server in the DMZ zone and I can run browse all the published apps from the LAN, even if I connect to the external IP. When I switch my laptop to the other network, where I am also in DMZ and all the ports are opened, I cannot connect nor browse applications. It is only possible to browse list of published apps with TCP/IP + HTTP network protocol selection, but still it is impossible to run them. I am using Windows Server 2003. Please help.
